For example:

New-NetLbfoTeam -Name "Team1" -TeamMembers "NIC1" -TeamNicName "Team1" -LoadBalancingAlgorithm Dynamic -TeamingMode SwitchIndependent -Confirm:$False

Will create an interface called "Ethernet" (Visible through Get-NetAdapter).

If you delete the team and recreate in the same DSC, it'll work correctly.

i.e. this works and creates an interface called "Team1"

$team1 = Get-NetLbfoTeam -Name "Team1" -ErrorAction SilentlyContinue;

            $teamExists = [bool]($team1);

            if(!($teamExists)) {

                New-NetLbfoTeam -Name "Team1" -TeamMembers "NIC1" -TeamNicName "Team1" -LoadBalancingAlgorithm Dynamic -TeamingMode SwitchIndependent -Confirm:$False;

                Remove-NetLbfoTeam -Name "Team1" -Confirm:$False;

                New-NetLbfoTeam -Name "Team1" -TeamMembers "NIC1" -TeamNicName "Team1" -LoadBalancingAlgorithm Dynamic -TeamingMode SwitchIndependent -Confirm:$False;

            }
